Rails Graphql resolve error: wrong number of arguments (given 1, expected 3)

I created fresh rails app with graphql, but had a lot of problems agains guides aged 6+ months. I suspect that graphql-ruby changing quite fast.

So my last issue in resolve method:

module Types
  class QueryType < Types::BaseObject
    graphql_name "Root Query"
    description "The query root of this schema"

    field :allProducts, [ProductType], null: false do
      resolve ->(_obj, _args, _ctx) { Product.all }
    end
  end
end

Error:

I'm using the latest version:

Ok, that resolve thing doesn't work anymore. Next code works fine:

class QueryType < Types::BaseObject
  graphql_name "RootQuery"

  field :categories, [Types::CategoryType], null: false

  def categories
    Category.all
  end
end
